Feature
Turbidity measurement Device Continuous measurement mode can be used for indexing or matching the sample vials. Auto-Power Off effectively conserves battery life.
Setup menu
lab Turbidity Meters Setup menu allows setting the 7 parameters, including the number of calibration points, resolution, date and time, etc. Reset feature automatically resumes all settings back to factory default options.
Stored data
Turbidity testing equipment Expanded memory stores and recalls up to 100 data sets. Stored data can be transferred into computer by USB communication interface. Multi-mode power scheme (battery, power adapter or USB port) ensures that use the meter smoothly.
Introduction:
High performance portable turbidity meter, 2 to 5 points calibration, selectable 4 turbidity units. The meter is suitable for process control and field use.
Package
Unpacking Before unpacking, ensure that the current work environment meet following conditions. Relative humidity is less than 80% Ambient temperature is greater than 0C and less than 60C No potential electromagnetic and ambient light interference
Operating Principles
portable turbidimeter operates on the nephelometric principle of turbidity measurement and is designed to meet the criteria specified in ISO 7027. The following figure shows basic optical system of the meter. It includes a light source and a detector to monitor the light scattered at 90 degree with respect to the incident beam.
